Separate I$ and D$ interface signals that span clock cycles
...
For example, Decopuled[HellaCacheReq].bits.kill doesn't make sense,
since it doesn't come the same cycle as ready/valid.

Changes to prepare for switch to TileLink interconnect
...
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.
* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect

separate btb response mask from the frontend mask
...
It is now the job of the pipeline to monitor the frontend's valid mask (of
instructions) and the BTB's suggested valid mask (based on the prediction it
makes). Some processors may want to ignore or override the BTB's prediction and
thus can supply their own instruction mask.
